GAS-STOVE.

SFECIFICATION forming part of Letters Patent No. 380,355, dated April 3, 1888.

Application filed July G, 1887.

.To di whom t may concern:

Be it known that l, JAMES L. SHARP, ofthe city, county, and State of New York, have iuvented new and useful Improvements in Gas- Stoves, of which the following is a full, clear, and exact description.

My invention has for its object certain new and useful improvements in gas-stoves.

The invention consists, rst, in a new form of burner. This burner consists ofa ring having two rows of cogs or teeth, one adjacent to each edge, and in a grooved ring or gutter, upon which theV cogged ring rests. Two branches of a gas-pipe enter this grooved ring or gutter, preferably diametrically opposite each other. The gas issues from the gutter between the cog-teeth, and, when ignited, burns within the ring and also on the outside of the ring, thereby forming a double iiame in one burner.

The invention also consists in an air pipe or tube adapted to surround the ends of two gaspipes, which are separated from each other, and in a perforated sleeve or diaphragm carried by the air-pipe, which sleeve surrounds the end of one or both of said gas-pipes, and also covers au opening in one side of said airpipe. Gas enters one pipe from the other after first passing through the air-tube, and air also enters the receiving gas-pipe through the air-tube and perforated sleeve or diaphragm and mixes with the passing gas, so that when the gas is burned a blue i'lame will be produced. rlhe perforated sleeve or diaphragm within the air-tube also serves to prevent ignition ofthe gas should it escape from the noixing-tube.

The invention also consists in details of construction, as will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part of this specication, in which- Figure 1 is a plan view of a gasstove enibodying my improvements. Fig. 2 is avertical cross-section on the line c c, Fig. l. Fig. 3 is a detail face View of the cog-ring. Fig. 4 is a cross-section taken through the air-tube on the line k k, Fig. 2; and Fig. 5 is a vertical cross-section on the line 7c 7c', Fig. 1, the part' B being removed.

A in the accompanying drawings represent-s Serial No. 243,484. (No model.)

the body portion cfa gas-stove, shown of circular form and carrying upon its top a removable utensil-rest, B; but the stove A may be of any other suitable shape, if desired.

Secured to the inner wall of the stove A is a short tube, D. lIhe tube D receives at its outer end a gas-nipple, c, of smaller diameter than the tube D. The outer end of the nipple a is adapted to be connected to the gas-suppl y pipe. (Not shown.) The tube D is cutaway on one side, forming an opening, b, for the admission of air. A perforated screen, d, is placed within or on the tube D and surrounds the opening Z1 in the tube D. Through this gauze screen air may enter the tube D around the nipple a. The inner end ofthe tube D receives the end of a pipe, e, for conveying the mixture of gas and air to the burner. The ends of the nipple a and pipe e within the tube D are separated a 'slight distance, so that air may enter the pipe c from the opening Z1. The gas passes from the nipple a through the tube D into the pipe e, mixing with the air in said tube. For facility of adj ustrnent of these parts, and to insure that the pipe c will be securely held by the tube D, I prefer to make the tube D iu the form of a clamp. (Best seen in Fig. fi.) In this case one half of D is cast or otherwise attached to the stove-body A. The other half, f, is a cap held in place by screws g, as shown. When the tube D is niade iu this forni and the parts a, d, and c are to be adjusted in the same, it is only necessary to first release the cap f, and after the adjustment is made the cap j' can be drawn up again by means of the screws g to tirmly clasp the pipe e,- but the pipe e may be otherwise held, if desired. The inner end of the pipe e enters a cross-pipe, 7L., which is provided on its ends with two upright branches, t' i, which enter a horizontal grooved ring or gutter, E, on lopposite sides of its center. A ring, F, rests upon the hollow upper side of the gutter E, and is secured thereto by means of screws or bolts j j, that pass through said ring, through the upright branches t' t', and through the lower part of the cross-pipe h, where they are secured by nuts, as shown, forming a ready means of attachment and detachment. rIhe heads of the bolts sink into the ring F. By this means the ringis firmly held in position. Thus the uprights t'- fi serve the double purpose of passage-way for the gas to fll IOO

the burner and for the bolts to hold the ring F in position, provided on its lower face with a double row of cogs or teeth, ZZ, which are situated along its outer and inner edges, respeetively. (Best shown in Fig. 3.) The oogs or teeth Z Z2 are arranged to rest upon the upper edges of the gutter E, so as to form outlets for the mixed air and gas between them. The

v gutter E and ring F when placed in position form a complete burner. The mixture of gas and air issues from the gutter E between the cogs H2 and the edges of the gutter E, and, when ignited, burns on the inner and outer edges of the ring F, thus producing a double ame in one burner.

The perforated sleeve d serves to prevent ignition of the gas should it escape from the mixing-tube.

Having now described my invention, what I inner edges, respectively, the gutter E, having plain upper edges carrying said ring, the two branches i z' on pipe h, which enter the gutter E on opposite sides, bolts jj, that pass through the ring F, through the branches z' 2, and through the pipe h, and the pipes e and h, substantially as described.
